求翻译：我想，如果能有一封澳大利亚的公司给我一份信（如Colin5年前给我的信，见附），说明我是公司派中国联系业务、开拓市场等等，需要在中国常驻，这将对延长签证会有很大的帮助。是什么意思？

I think if there is an Australian company gave me a letter (eg letter to me colin5 years ago, Annex), I send Chinese business links, market development, etc., in the Chinese Permanent Mission, which will extend the visa will be very helpful.

正在翻译，请等待...
